Product Details

TotalBoat Penetrating Epoxy is a low-viscosity wood rot restoration and repair solution that seals deeper & cures stronger than industry-leading penetrating epoxies. It has no VOCs, no odor & is 100% waterproof once cured.

This 2:1 system is ideal for restoring rotten or damaged wood, or sealing new wood for lasting protection against humidity, salt, mold & mildew. It works by gluing cellulose (wood) fibers back together, sealing a bare, porous wood surface from the inside out. Double the penetrating power by mixing acetone with the epoxy resin solution in equal volume. Easy to apply by brush, roller, or inject via syringe. Surfaces may be painted or varnished after light sanding.

Choose from Traditional (65-90 F) or Cold Weather (40-65 F) formulas in Pint, Quart, 1/2 Gallon & Gallon kits.

Info & Guides

NO VOCS, NO SMELL.

Cleanup is easy. Wear latex gloves, wash off with soap and water. No solvents required.


APPLICATION NOTE: The wood must be bare and unfinished. Also, TotalBoat Penetrating Epoxy will not penetrate and level well when applied over some stains. Always test an area first. DO NOT USE on top of Minwax oil-based stains.


TotalBoat Cold Weather Penetrating Epoxy is perfect for use during the colder seasons. Compared to our traditional TotalBoat Penetrating Epoxy, our Cold Weather formula offers similar performance characteristics, but cures completely and reliably in cooler temperatures. Its tack-free properties also allow you to sand sooner.

WARNING: TotalBoat Cold Weather Penetrating Epoxy should not be used as a fast-cure epoxy in warmer temperature conditions because doing so can be unsafe and result in premature exotherm, brittleness, and improper curing.

Application Temperature Ranges:

  • Traditional formula - 65-90°F
  • Cold Weather formula - 40-65°F

Great product to fill pourus wood
By SWFloridaBoater from Englewood Florida

Verified Purchase

I bought this to fill holes in some house framing that was attacked by termites. No smell. Very liquid and hardened very well. Actually had to trim one of the studs I had filled and coated and my oscillating tool had a rough time trying to cut through it.

took a while
By double bourbon from Grinnell, Iowa

Verified Purchase

Except for the hardener bottle being miss labeled the product seems to have worked well. The hardener bottle was labeled one quart when in fact it was two quarters as it was supposed to be for a proper 2 resin to 1 hardener mix ratio. Fortunately I mixed it that way and was correct. I verified that by pouring 2 quarts of water from a juice bottle into the hardener bottle.

Bottom Line Yes, I would recommend to a friend

A remarkable solution to a nasty problem!
By Acemotorman from Ft. Worth, TX

Verified Purchase

The chipboard bottom of the compartment where city water connects to our 5th wheel became saturated when a hose gasket failed. Once dried out, I mixed the TotalBoat Penetrating Epoxy per the instructions; drilled a few 1/8" holes in the wood and poured the epoxy down the same path the water took. It dried in a little over one day; is rock solid and more importantly, can't be damaged in the same way again. It worked better than advertised!

Bottom Line Yes, I would recommend to a friend

Excellent Product
By Mark from Houston Texas

Verified Purchase

I used this to seal a white oak sailboat rudder that I made. The epoxy soaked into the raw wood beautifully and the high gloss finish was achieved after only two coats.

Bottom Line Yes, I would recommend to a friend

old boat restoration
By Mike the boatman from Lake Arrowhead, ca.

Verified Purchase

I am restoring a 1954 Glen L. Witt outboard runabout. All wood construction. The deck is plywood and I took it down to bare wood. Then I used penetrating epoxy (thinned 50/50 with acetone) to firm up and prepare for varnish. The thinned epoxy penetrated deep into the plywood and the whole structure feels much stronger. I have now put on two coats of varnish (at least one more to come) and it looks fabulous.

Bottom Line Yes, I would recommend to a friend
